I'm pretty new to this forum and Audi's in general. My Audi has a few issues but the one that I think is the worst is when I'm driving straight it makes a squeaking noise and vibrating sort of noise. Kinda like one of my tires are flat or something. The vibration noise gets worse when i turn the wheel left. Someone told me it could be the CV joint or something. I'm not sure really. Any ideas? Is it safe to drive? It never vibrated like this until one night i drove on the highway about 20 miles and back. Any help would be appreciated. Thanks
